With a career spanning international organizations, governments, and multilateral forums, she has advanced agendas at the intersection of equity, innovation, and global solidarity. She has contributed to high-profile initiatives with the World Bank, UNFPA, ECDC, and the Lancet Commission, and currently serves on the Board of Women in Global Health.
